BMW USA has launched a promo video at the beginning of June to show what’s new for ‘the most powerful letter in the world’. If you’re a BMW fan or just like cars in general, the letter ‘M’ and the number ‘6’ combine to create two of the most exciting models in the world right now.

Both the F12 M6 Coupe and the F13 Convertible are new to the US market, and the representative of the M brand says that only 20% of the parts are shared with the 650i top-of-the-range 6-Series.

Probably the most exciting news for 2012 is that you can enjoy that performance as a daily driver, as the new 4.4-liter twin-turbo V8 that’s been put into the car is almost 30 percent more efficient than the old V10, which means it makes for a better GT car.
